Class ImplicitExceptionsPlugin

java.lang.Object

com.oracle.svm.hosted.phases.ImplicitExceptionsPlugin

All Implemented Interfaces:

org.graalvm.compiler.nodes.graphbuilderconf.GraphBuilderPlugin, org.graalvm.compiler.nodes.graphbuilderconf.NodePlugin

public class ImplicitExceptionsPlugin
extends Object
implements org.graalvm.compiler.nodes.graphbuilderconf.NodePlugin

Exceptions that are thrown implicitly by bytecodes, such as NullPointerException, are thrown frequently in nearly all methods. Having an explicit object allocation in every method would lead to code explosion. Therefore, we have one cached instance of every such exception class. To keep the generated code as small as possible, the cached exception is thrown by a runtime method.
